\begin{frontmatter}
\maketitle
\begin{abstract}
The design for the \emph{Annals of Glaciology} has been implemented as a \LaTeXe\ class file and is derived from article.cls. We recommend that authors use this guide as a template. While writing we suggest you use the two-column \texttt{[twocolumn]} option to check that mathematical equations fit the measure. Submitted papers must, however, be presented using the one-column \texttt{[review]} option. If you have any problems using the class file, please contact Overleaf support at \texttt{www.overleaf.com/contact}. The abstract should be less than 200 words and one paragraph long.
\end{abstract}
\end{frontmatter}
\section{Using the IGS class file}
Please ensure you have downloaded the latest version from http:/$\!$/igsoc.org/production/. The IGS \LaTeXe\ annals guide has examples of most environments authors are likely to come across. The title page contains some new environments, e.g. affiliation and abstract. Papers should be divided into unnumbered sections with short section headings. SI units and internationally recognized systems of abbreviation should be used throughout. The \TeX\ file should be named to reflect your paper number, i.e. 72A712.tex. Please remove any extraneous text (e.g. text from previous drafts, notes and comments that will not form part of the final printed text of the paper).
\subsection{Typesetting the title page}
In the IGS design, shortened versions of the title and authors are used in the running head. The shortened version is specified in square braces immediately after the \verb"\title" and \verb"\author" commands (see below).
\begin{verbatim}
\title[Short Title]{The Full Title of Your Paper}
\author[Short Authors]{Author 1, Author 2 and Author 3}
\end{verbatim}
\subsection{Lists}
The IGS class file provides for numbered (\verb"enumerate") and unnumbered (\verb"itemize") lists. Nested lists are not encouraged. The default numbering system is 1., 2., 3., etc.; please do not change this unless there is a good reason. The IGS design removes bullet points from unnumbered lists.
\subsection{User-defined macros}
If possible, please do not define any new macros.
\begin{table}% table1, one column
\caption{One-column table captions will extend beyond
the rules in two-column format. Do not try to adjust!
Table captions do not have full points at the end}
\label{period}
\begin{minipage}{86mm}% you only need this line if you
% have a table footnote
\begin{tabular}{@{}lcc}\hline
Period\footnote{Please do not use more than one `\&'
between columns, and note that if a table includes
table footnotes, it must be inside a \texttt{minipage}
environment.}%
& Surface elevation change
& Emergence velocity\\ \hline
1975--85 & $-0.50$ & 0.43\\
1986--2002 & $-1.03$ & 0.32\\
Difference & $-0.53$ & \llap{$-$}0.11
\end{tabular}
\end{minipage}% you only need this line if you have a
% table footnote
\end{table}
\subsection{Tables}
Tables may be typeset in either one- or two-column format. To typeset two-column format, add asterisks\\
(\verb"\begin{table*}...\end{table*}") as shown in Table~\ref{seasonal}. We may change the format in-house if necessary. Please avoid the use of colour or shading. Note that if you choose to refer to tables using labels, \verb"\caption" must precede \verb"\label", as in standard \LaTeX. Vertical rules are not house-style and will be removed. Note the use of the minipage environment in Table~\ref{period} which enables table footnotes to be output. If the table is two-column, use \texttt{\{178mm\}} instead of \texttt{\{86mm\}} on line~6. The source code for Tables~\ref{period} and~\ref{seasonal} is shown immediately below the tables.
\begin{table*}% table2, two column
\caption{Two-column table. Seasonal and annual SAT trends ($^\circ$C\,decade$^{-1}$) in the Arctic}

\hline
\end{tabular}
\end{table*}
\subsection{Figures}
Figures may be typeset in either one- or two-column format. One-column format allows up to 86$\,$mm (e.g. Fig.~\ref{tracks}); two-column format up to 178$\,$mm (e.g. Fig.~\ref{filters}). Please do not provide original graphics files in which the figure is a great deal larger or smaller than what you envisage will be the final printed size. To typeset two-column format, add asterisks (\verb"\begin{figure*}...\end{figure*}") as shown in Fig.~\ref{filters}. We may change the format in-house if necessary. Please note that if you choose to refer to figures using labels, \verb"\caption" must precede \verb"\label", as in standard \LaTeX.
Please send one file for each figure (in other words do not use subfigures) and use a name that clearly identifies it (e.g. `72A712Fig03.eps').
In addition, figures should be eps, ai (illustrator), ps, tif, psd or pdf. Use strong black lines with a width of at least 0.75pt at final printed size (avoid tinting if possible) and SI units in labels. Lettering should ideally be Optima to match the final typeface; Arial or a similar sans serif font for a second choice. Aim to have the final-size lettering at 9pt, if possible. Figures should not be in boxes. The source code for Figs~\ref{tracks} and~\ref{filters} is shown immediately below the figures.
\subsection{Equations}
We are including some complex equations as examples. Equations should be checked for width by removing the \verb"[review]" option. Note the use of \verb|cases*| in the following equation:
\begin{equation}
\label{arrayexample}
\alpha_{t_2}= %
\begin{cases}
\alpha_{t_1} - a_1 [\ln (T+1)]
\mathrm{e}^{(a_2\sqrt{n})}
& \mbox{$n_\mathrm{d} > 0\enskip$ and
$\enskip T > 0$}\\
\alpha_{t_1} - a_3 \mathrm{e}^{(a_2\sqrt{n})}
& \mbox{$n_\mathrm{d} > 0\enskip$ and
$\enskip T < 0$}\\
\alpha_{t_1} + a_4 P_\mathrm{s}
& \mbox{$n_\mathrm{d} = 0$}
\end{cases}
\end{equation}
Equations should be aligned on the equals signs where possible. Equations that extend beyond the one-column measure should be turned over before an operator.
\begin{equation}
\label{eqnarrayexample}
\begin{aligned}
l_c & = l_0 \left(\frac{\widebar{R}_m}{R} \right)^2
\psi^{\frac{P}{P_0\cos Z}}\\
& \phantom{=} \quad \times [\cos\beta\, \cos Z
+ \sin\beta\,\sin Z\,\cos(\psi_\mathrm{sun}
- \psi_\mathrm{slope})]
\end{aligned}
\end{equation}
\subsection{Typesetting upright Greek characters}
Normal greek: \verb|$\alpha\beta\gamma\delta$|
$\alpha\beta\gamma\delta$
Upright greek: \verb|$\upalpha\upbeta\upgamma\updelta$|
$\upalpha\upbeta\upgamma\updelta$
Usual partial: \verb|$\partial$| $\partial$
Upright partial: \verb|$\uppartial$| $\uppartial$
\subsection{Marginal notes}
The IGS class file\marginpar{Editor! Help!} redefines the \LaTeX\ command \verb"\marginpar". If you wish to add a marginal note such as the one alongside this text, you would key \verb"\marginpar{Editor! Help!}". Marginal notes will be removed before printing.
\subsection{References}
All citations in text should include the author name(s) and the year of publication (e.g. `Smith, 2014'; `Smith and Jones, 2014'; `Smith and others, 2015') and have an entry in the reference list.
References should:
\begin{itemize}
\item be short;
\item be complete and accurate;
\item be arranged in alphabetical order by first author's surname;
\item include too much rather than too little information;
\item include doi numbers where available (note that older bib databases often included doi's in the page field -- in which case they may appear after a comma and without braces);
\item include works accepted but not published as `in press';
\item not include personal communications, unpublished data or manuscript in preparation or submitted for publication, data published on the web (these should be included in the text).
\end{itemize}
\begin{figure}%fig1, one column
\centering{\includegraphics{72A712Fig01.eps}}
\caption{One-column figures should be $\leq$86$\,$mm.
Good artwork can make or break a paper. Capitalize
the first word of a label and use round not square
brackets for units.}
\label{tracks}
\end{figure}
\subsubsection{Automatic references using \textsc{Bib}\upshape{\TeX}}
To generate automatic references from a bib database, you must first specify the database (we are using \verb"igsrefs.bib") and then the IGS bibliography style by placing the following two commands where you would like the references to appear (normally at the end of your paper, before \verb"\end{document}"):
\begin{verbatim}
\bibliography{igsrefs}
\bibliographystyle{igs}
\end{verbatim}
%
Then run through the following steps:
\begin{enumerate}
\item Run your paper through \LaTeX.
\item Run \textsc{Bib}\TeX\ on your paper.
\item Open the newly-created bbl file containing the cited references and copy the entire contents to just below the \verb"bibliography"/\verb"bibliographystyle" commands.
\item Then comment them out:
\begin{verbatim}
%\bibliography{igsrefs}
%\bibliographystyle{igs}
\end{verbatim}
\item Run your paper through \LaTeX\ \textit{twice} more.
\end{enumerate}
The IGS do not need your bib or bbl files. Note that \textsc{Bib}\TeX\ will lose the second initial in the entry `Box JE', for example, if it has been typed as `\{J.E.\} Box' in the bib file. This is because any text in an entry enclosed in \{\,\} will be treated as a single unit, and will not be further parsed. Prof. Box's name will typeset correctly if entered as `J. E. Box' in the bib file.
If you have cited 16 references from the bib database, e.g.
\citep{Rignot08},
\citep{Rignot08_2},
\citep{Motyka11},
\citep{Morlighem10},
\citep{Morlighem11},
\citep{Seroussi11},
\citep{Yan13},
\citep{Rogozhina12},
\citep{Hanna13},
\citep{Goelzer13},
\citep{Lucas12},
\citep{Edwards14},
\citep{gladstone_grl_10},
\citep{Morlighem13},
\citep{Goldberg11} and
\citep{paterson94}, the output will be just those 16 references and they will appear at the end of the article.
\paragraph{Citations using natbib commands}
Note that the standard natbib style file has been modified to fall into line with IGS style. The modified style file is called igsnatbib.sty (included in this distribution), and works exactly the same as natbib.sty. The default IGS house style is \citep{Yan13}. The following combinations are also available -- refer to the natbib documentation if you require any further explanation:\\*[0.5\baselineskip]

\section{Appendix}
Start an appendix by \hbox{typing \verb"\appendix\section{Appendix}".} Appendices appear after the references. Equation numbers automatically start again with (\ref{appeqn}).
\begin{equation}
\label{appeqn}
2\eta\kappa \frac{\partial \skew1\bar u}{\partial t} + \rho_{\mathrm r} g \skew1\bar u + D\kappa^4 \skew1\bar u = \skew3\bar\sigma_{zz}.
